Abstract

PURPOSE:To improve utilization of active substance by forming a plate where a substrate is impregnated with active substance through deposition impregnation method with specific charging current and discharging current thereby activating the active substance of said plate. CONSTITUTION:A nickel anode plate where a sintered nickel substrate is impregnated with nickel active substance through deposition impregnation method is immersed in potassium hydroxide or sodium hydroxide solution having specific gravity of 1.2-1.3. Then it is charged with current of 1-10C and discharging amount of 150-200% while discharged with current of 1-10C and discharging amount of 50-75% and said formation is repeated for 1-2 times. The reason of employing 1-10C of current is that the activating effect of active substance is low if discharging current is lower than 1C while active substance having high expansion/shrinkage due to charge/discharge may drop from the substrate core body or the plate will expand if the discharging current is higher than 10C.
